MACHINE FOR TREATING GRAIN.

Specification of Letters Patent.

Application filed July 29, 1908.

Patented J uly 5, 1910. Serial No. 445,915.

To all whom it may concern:

-Be it known that I, Ronnnr IIARr,'of Ardoch, in the county of Walsh andState of North Dakota, have invented certain new and useful Improvementsin Machines for Treating Grain; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appcrtains to make and usethe same.

This invention .relates to a machine for treating grain,the object ofthe invention being to provide eflicient means for removing dirt andfoul seeds and for treating the grain for smut.

A further object is to so construct a machine of the character describedthat a continuous flow of wateror other fluid can be effected and sothat the same water or other fluid can be used repeatedly, especiallywhen it is desired to subject the grain to some chemical treatment.

With these and other objects in View the invention consists'in certainnovel features of construction and combinations of parts as hereinafterset forth and pointed out in the claims.

Ir the accompanying drawings, Figure 1 is a side elevation of a machineembodying my improvements. Fig. 2' is a vertical sectional view. Fig. 3is a similar view at right angles to Fig. 2, and Fig. 4 is a plan viewof the hopper 17.

1 represents a framework in which, be tween the top and bottom thereof,a trough 2 is secured and provided with an upwardly projecting, inclinedchute 3. The side walls of this chute are provided at their upper endswith bearings for a shaft 4 having wheels 5 secured thereto for thepassage of an endless conveyer G. This endless conveyer extendsdownwardly into the trough and passes over wheels 7 secured to a shaft 8mounted at its ends in the side walls of said trough. The shaft 4projects beyond its bearing in one of the side walls of the chute and isprovided with a pulley 9 to re ceive a belt 10 by means of which motionis transmitted to the conveyer from a pulley 11 on a shaft 12 mountedupon the framework 1. The chute 3 is provided with a false bottom 13having perforations 14 through which water which may be elevated withthe rain from the trou h can ass. Such water will flow downwardly overthe bottom of the chute and be discharged from the lower end thereofinto a receptacle 16 secured in the bottom of the framework.

A vertically adjustable hopper 17 is lo- I cated in the upper portion ofthe framework and is adapted to receive the grain to be cleaned. Theinclined bottom 18-.of this hopper is movable in order to regulate theflow of grain from the bottom of the hopper to a grooved feed roller 19mounted under said bottom of the hopper. A slide 20 is 10- cated againstthe vertical wall of the hopper so that it will be adjustable withrelation to the feed roller and thus control the speed and quantity ofthe feed of the latter. It will be observed that the grain hopper islocated directly over the trough 2. Also located over said trough anddisposed alongside the hopper is a smaller trough 21 hav ing a series ofholes 22 in proximity-to its bottom through which water from the trough21 can flow into trough 2. The holes 22 are arranged at differentdistances from the bottom of the trough so that by means of a gate 23the quantity of water flowing from said trough can be accuratelyregulated. By making the hopper 17 adjustable vertically, the extent offall of the grain can be increased or decreased according to thecharacter of the grain under treatment and the amount of fall necessaryto force the grain through the current of water flowing from the trough21. Trough 21 is movable so that it can he slid horizontally to and fromthe flow of grain from hopper 17 and thus increase or diminish theagitation on the surface of the water in trough 2, the object being tohave the grain drop on a smooth surface of water and sink through thewater leaving the dirt and foul seed to float off on top of the water intrough 2.

In order to rotate the grooved feed roller 19 one journal thereof isextended beyond its bearing in the side wall of the trough 2,and isprovided with a pulley 24 over which a. belt 25 passes, said beltreceiving motion from a pulley 26 on the shaft 12. The shaft 12 may beprovided at one end with any suitable means for receiving motion fromany source of power. In the drawing I have shown said shaft providedwith a crank arm 27. The other end of the shaft 12 projects beyond theside of the framework and is provided with a pulley 28 for theaccommodation of and for operating a water elevator 29 inclosed within asuitable housing 30 secured to the side of the framework. This waterelevator (which may be of any pre ferred construction) communicates atits lower end with the water receptacle 16 at the bottom of theframework and at its upper end, said. water elevator discharges, througha pipe 31 into the upper water trough 21. An overflow pipe 32communicates at one end with the upper ortion of the trough 21 and atits lower end is charges into the water receptacle 16. A screening box15is located over one end of the water a receptacle 16 and is designed-tointercept the seed or other solids which might overflow with the waterover the end of the water trough 2. Y

From the construction and arrangement of parts above described, it willbe observed that grain from the hopper 17 and water from the trough 21will flow simultaneously into the trough 2. When barley or oats are tobe treated a roller 33 is mounted in said trough 2. T 's roller islocated in proxim= ity to the point where the barley or oats strikesthewater so that the same may engage it and be carried under the surfaceof the water. The roller 33 is provided with journals mounted in plates34 and. the latter are provided with slots 34 for the reception ofbolts' 35 having nuts 36' whereby saidplates can be secured in anydesired vertical 3 adjustment to cause the roller to dip more or less inthe water in the trough 2, and to permit said roller to be raised abovethe surface of the water, as it will be when grain, other than barley oroats is beingl treated. Hangers 37 are supported within t e trough 2 bythe journals of the roller 33, and to these hangers, scrapers 38 for theroller, are attached. The hangers 37- are made with slots 39 to receive,the bolts 35', and in this a manner, said hangers are prevented from.water finding its wa rations in the false will also be thoroughl Acleansed "of smut.

turning. "One journal of the roller 33 is 45' provided with a pulley 40,which receives motion, through t e medium of a strap 41, from a pulley42; As the grain settles in the vbottom of the trough 2 it will beremoved ,again' be conveyed by the water elevator and discharged intothe trough 21, so that the same .water may be used over and again intreating grain. This is especially valuable in the water during thetreatment of the grain.

Various slight changes mi ht be made in the details of construction 0 minvention without departing from the s 1rit thereof or limiting 1tsscope and hence do not wish to restrict myself to the precise detailsherein set forth.

Having fully described my invention what I claim as new and desire tosecure by Letters-Patent, is,-
